Be it known that I, JAMES G. `HALL, a

citizenl of the vUnited States, residing at Burlingame, in the county of San Mateo and State of California, have inventedcer-v tain new and useful ylinprovements in Books, of whichthe following is a specification;

This invention relates-to a mapor guide in a convenient folded z or Ibook form, en,n abling' the ready examination of the map or guide without unfolding-'the entire sheet and spreading the saine, as is the present custom. l

The present invention has for its principal object to provide a map or guide folded into a small compass and arranged in connected sections, each in page form, foldable centrally on right angle creases, enabling the ready reference to section and page' when it is desired to locate any particular place on the map or guide.

By my present invention, the permanent folded arrangement of the sections and the dividing of the same into pages affords a support or rest for the various section leaves or pages, enabling but a small portion of the l entire map or guide to be exposed in loeating any desired point thereon or in following any road or indicated path. An

other of the important and essential objects is to provide a map or guide folded in book form and adapted to be carried in the pocket `and for use by aviators when flying or motorists when touring without exposing a great area of the map to the wind action, thereby enabling the easy examination of any desired portion or page without the wind interfering with the reading thereof.

A further object is the folding of a relatively large map or guide into a small compass in such manner that the contiguous portions of the map or vguide are contained on adjacent pages and are capable of eX- vamination by the'folding of the pages on the intersecting creased lines. f

With the above mentioned and other objects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings and pointed out in the claim hereto appended; it being understood that various changes in the form, proportion, size and minor details ofvconstruction Within the scope of the claim may be Y lSpecicafti'oii cf LettersjPatent.

"To more vclearly comprehend theqinven#v tion, reference is directed tothe accompanyl,

ing drawings, wherein :f-v f Figurel is a view intop plan ofa map folded into three 'connected'sections in ac-` cordance with my invention, illustrating the baclror coverv secured to the terminal edgesl F'gure is anedge view of themap be. x j tween .adjacent sect1ons,''illustratingM-the.

manner of folding the same in forming the leaves. j

Figure 3 is a view in elevation of one of the leaves, illustrating the creases therein. i

i Figure i is auview in elevation ofyone `of the sectors illustrating `one of the leaves in raised position.

Figure 5 is a fragmentary view'in detail planof the `map or guide illustrating one of the cuts or slots therein and the direction of folding the body at either side thereof. c

In the drawings, wherein like characters of reference designate corresponding parts 170]' intersecting f Y throughout the several views, 1 indicates a li sheet provided on one face or surface with map or guide matter as desired, and the same in providing the connected sections is cut or slit vertically. as at 2, the cut terminating short of the upper and lower edges ofthe sheet providing section connecting or hinged portions Sand i at the opposite ends of each cut. The vertical cuts are located at uni-` form distances from each other to provide a plurality of leaf forming sections 5l of uniform width and yextending 'vertically of:

manner providing a series of leaves disposedV transversely of each section 5. After being folded, the vertical sections 5 are longitudinally-creased in their center as at 10, so that the opposite halves of the faces will fold into contact, and the connecting or hinge portions 3 and 4 providing adjacent sections vvare creased to permit the backs of adjacent halves of adjoining strips to lie back to back. The sections may be carried out to any number dependent on their width and the width of the sheet, and the leaves may be carried out to any number' dependent also on their width and the depth of the sheet.

The rear surface of the top and bottom folds 7 at their' extreme opposite side edges of the sheet are adhesively or otherwise secured or attached to the inner surface of the hinged cover members ll, thus when the s cover is closed the folded map or guide is in book forni and to examine the same it is only necessary to turn the half sections on the longitudinal creases 10 to refer from one section to the other, and, when the desired section is located, to turn the traiisverse leaves 9 on their hinges to expose the desired spot on the map or guide.

lt will be observed that the leaves of any selected section contain a vertical strip of the map or guide, and that the portion of the map or guide at either side of any selected portion on the leaf may be located by turn-` ing to the adjacent section and turning the leaves thereof until the corresponding leaf of the adjacent section is exposed.v

Having thus described my invention,'wliat l claim as new anddesire to protect by Letters Patent of the United States is A book consisting of a sheet divided vertically into a plurality of sectionsconnected at their opposite ends, each of saidy sections being folded transversely to provide a plurality of outwardly extended hinged leaves, said sections being centrally creased verti cally through said leaves to provide half portions adapted to fold face to face, said section connecting portions of the sheet being vertically creased to permit corresponding half portions of adj acent sections to fold back to back, and a cover to which the terminal end portions of the top and bottom of said sheet are attached.

ln testimony whereof I have signed my name to this speciflcation.

JAMES G. HALL
